3/38-3/7<br> 2+1/35<br> 3/56+3/2
prohojiy [21]

Answer:

87/56

Step-by-step explanation:

Simplify the following:

3/56 + 3/2

Put 3/56 + 3/2 over the common denominator 56. 3/56 + 3/2 = 3/56 + (28×3)/56:

3/56 + (28×3)/56

28×3 = 84:

3/56 + 84/56

3/56 + 84/56 = (3 + 84)/56:

(3 + 84)/56

3 + 84 = 87:

Answer:  87/56

Larry read a 400400400-page book. He read at a rate of 101010 pages per day for ddd days. Write an equation that could be used t
ira [324]

Answer:

From Larry's rate, the equation can be given as D = T/101010

Step-by-step explanation:

Larry's book has 400400400 pages

His reading rate is 101010 pages per day

Let D = Number of days to read the book

To get the number of days it takes fro Larry to read this book, we say

Total pages = Reading rate (pages/day) x Number of days

Let Total pages = T

and Reading rate = R

Hence;

D = T / R

From Larry's rate, the equation can be given as D = T/101010.

From the question,

ddd = 400400400 (pages) / 101010 (pages/day) = 3963.9 days

Hence, it takes Larry approximately 3964 days to read the book.
